The material does cause a hazard beyond that caused by an ordinary combustible material. 2 at 3o'clock: Ignition occurs on heating to high temperatures. Intense exposure would lead to temporary incapacitation. Unstable material and reacts violently with water. 4 at 9o'clock: The material burns in air at normal
